Let's divide 806424 by 20
We want to figure out the number of times 806424 can be divided by 20.

Step 1:
20 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 20

Advancing to step 2:
When dividing 80 by 20, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 0 after subtracting 80 from 80.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 20

Step 3:
When dividing 6 by 20, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 20

Advancing to step 4:
The number 20 fits into 64 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 403.0
Deduct 60 from 64 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 20

Moving on to step 5:
42 divided by 20 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 4032.0
Subtracting 40 from 42 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 20

On to step 6:
If we divide 24 by 20, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 40321.0
Deduct 20 from 24 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 20 fits into 40 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 40321.2
Deduct 40 from 40 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40321.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40321.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 40321.2 with a remainder of 0.0.
